I was detained in Auschwitz from 23 June 1943 to 30 July 1943, and then transferred to a subcamp in Dwory, subordinate to Auschwitz. I stayed there until 4 May 1944, but I do not know the SS men from the list presented to me. I only know the name Grabner, but I do not know what function he held in the camp. In any case, he was a non-commissioned officer.
However, I do not know if this was the same Grabner as the one on the list. I have no knowledge with regards to the crimes committed against prisoners by the above-mentioned Grabner. Stanisław Malański, residing in Tarnów at Świętej Anny Street, and Julian Trzpis, residing in Tarnów at Ujejskiego Street 24, could provide more detailed information.
